Hypothesis: when potato chips are placed in solutions with high concentrations of sugar (for example 0.8 mol L-1) then they will lose mass as the chip will lose water because of osmosis. Conclusion: my results showed that the chips gained mass in water and low sugar concentrations but lost mass in high concentrations of sugar.
